Draw arrowhead without line

[julia.langeT5493]

Hi,

I would like to insert only arrowheads. Is this possible? I have tried to insert an "mleader" and to either change the landing distance or set the linewidth to 0.0 mm, but this does not work. I could just draw triangles as arrowheads, but maybe there is a more elegant solution.

My aim is to draw streamlines, thus creating curved lines and add the arrowhead at some positions.

I am looking forward to your proposals!

Kind regards,

Julia

Hi,

You can draw arrowhead with PLINE command ( Width option ) .

Command: PL PLINE
Specify start point:
Current line-width is 0.0000
Specify next point or [Arc/Halfwidth/Length/Undo/Width]: w
Specify starting width <0.0000>: 

Specify ending width <0.0000>: .2

Specify next point or [Arc/Halfwidth/Length/Undo/Width]: <Ortho on>
Specify next point or [Arc/Close/Halfwidth/Length/Undo/Width]:

Hi,

You can create a block and then insert the block on top of the lines.

Thank you very much! The PL (PLINE) is much easier to handle than my rectangles...

If you want to insert an arrowhead of dimstyle already in use, then arrowhead is automatically created block with name _Open30 or _Oblique, or DatumFilled... Look into the INSERT gallery for blocks with an underscore prefix.

Julia,
"My aim is to draw streamlines"
Using >>>Measure/Divide<<< with a triangle block will do this perfectly.

Hi,

OK, following up with this I would use a linetype with automatically showing the symbols along a line ;)))

If you mean equally-spaced positions, MEASURE or DIVIDE, or better yet a linetype definition or an associative ARRAY, would do.  [The linetype and associative ARRAY approaches are better because the arrowheads will adjust their quantity and direction appropriately if you change the shape of the streamline.]

If you want to select locations that are not equally spaced, a routine could be written that would ask you to pick locations and would do the INSERTing of a Block for you, including aiming it in the direction of the streamline at that point.  [I already have something that does that with Text labels, which could be modified easily enough.]
